Rising raw material costs are driving prices up

Resins are a critical component in the manufacturing of printing ink. They provide the characteristics that enable inks to transfer on to the press effectively, provide gloss and certain key resistance qualities, and allow colorants to adhere to substrates.

Resins are available in many different chemistries, depending on the systems in which they are being utilized. There are rosin derivatives and phenolics for offset inks, polyamides and nitrocellulose for flexo and gravure, and polyester, polyurethane, fumaric rosin esters and acrylics for water-based inks.

Many of these resins have their roots in crude oil, which has shot up dramatically in price. As such, resin manufacturers are attempting to increase their prices to meet higher raw material costs. For printing ink manufacturers, who are facing ever tighter margins due to low pricing, this is difficult news indeed.

Price Increases

The costs of raw materials that go into resins have increased, and, added to the fact that resin prices have been held in check for many years, the market is set to rise.

"Current market prices for resins are not reflecting the increased cost of raw materials used in all resins," said Pete Samuelson, business manager of solvent-and oil-based products for Lawter International, which initiated a price increase as of June 1 that affected all of its product lines. "While the goal of new developments includes improved economics, cost increases in petroleum derivatives and other raw materials used in both hydrocarbon and rosin-based resins will force prices up in the market. We expect prices to increase on all resin types due to sustained raw material cost increases beginning in the last quarter of 1999 and continuing through this year."

"Raw material price increases have strongly affected the graphic arts resins market during the last quarter of 1999 and the first quarter of 2000," said Francois Gallouedec, marketing manager, ink resins and additives, Cognis Corporation. "With solvent prices and gasoline prices on the rise, in addition to other raw materials which have not completed their round of increases, it is difficult to forecast where the rest of 2000 will take us."

"We are anticipating a third quarter general price increase in the range of 5 percent," added Robert O'Toole, business manager -- energy cure chemicals for Cognis Corporation.

"One of the things we're concerned with is that there is not a whole lot of upper movement in prices from our customers to their customers," said Chuck Mateer, market manager for SMA(r) resins for Elf Atochem, which is expected to change its name to AtoFina this month. "Meanwhile, our raw material prices are up significantly. Styrene has doubled in price since last year, and maleic anhydride is increasing."

"In the last eight months, everybody that uses styrene or maleic anhydride product has seen their prices rise considerably," added Dave Barbieri, Elf Atochem's business manager, functional polymers.

"Although certain raw materials are going up, including oil derivatives like phenols, I don't expect much movement on the rosin resin front this year," said Kees Riphagen, marketing manager for Akzo Nobel Resins. "Solvent-based products are a different story."

The low margins have a wide range of impact, from consolidations to reducing R&D. This also will have an adverse effect on ink manufacturers.

"Prices will need to rise as the very low margins being obtained today are stifling new developments and minimizing investments," said Mike Wicken, managing director of Mitchanol International Ltd. "The market must appreciate that cost-effectiveness does not come from price alone. The ink market has endured a steady consolidation of ink makers into a few global players. The resin industry is following suit. This will not mean efficiency in the future. Less players, less choice!"

There will be resistance to cost increases, but there is only so much that can be cut in production costs. Industry leaders believe that even with improved production efficiencies, there are more price increases on the way.

"It is very difficult to pass increased costs through the system," said Rick Grandke, technology manager at Johnson Polymer. "We are all being challenged to take costs out of our systems to keep prices as low as possible."

"While we strive to manage costs at all levels and in manufacturing, we have experienced significant raw material price increases over the last two quarters," said Holly Hartschuh, worldwide marketing manager, graphic arts, Robin and Haas Company. "We expect this trend to continue at least through the end of the year and therefore will be announcing price increases in the near future."

"One thing is for sure, we have not seen the last of the resin price increases for 2000," concluded Mr. Galloudec.

What's New

Despite the tight prices, resin manufacturers are actively working to meet market needs, including improving pigment wetting and faster press speeds.

Norm Szalkowski, chemist for Neville Chemical, said the company is "endeavoring to create the next generation of LX-2000, Neville's premier pigment wetting resin. Flush manufacturers and ink companies have always clamored for the ultimate universal pigment wetting resin that is utilizable in dispersing and wetting every process color and carbon black."

"On the let-down vehicle side of the business, the interest in self-structuring or highly visco-elastic resins persists," Mr. Szalkowski said. "Phenolic condensate modified hydrocarbons, with or without rosin hybridization, have also piqued the interest of ink makers who believe such resins can abate lithographic headaches in the pressroom (i.e. ink-water balance, feedback or roller build-up). Digitalography, the newest, fastest growing printing process, has tacitly moved into the mainstream and has all litho ink makers and their suppliers surveying that unique aspect of printing and strategizing how to bring it into the conventional ink maker's fold."

"Printing ink manufacturers are constantly in search of higher performance resins to be used in inks to be run on high speed presses on varying qualities of paper," said Dan DeLegge, technical director, resins at Lawter International. "Misting, water balance and flow are their main concerns. The new technologies revolve around the expansion of structured high molecular weight resins, with improvements in the stability of rheology.

"In the liquid ink area, improvements such as heat resistance, lamination, flexibility, lower VOC and resistance to chemicals, oils and solvents are of paramount importance with a emphasis on water-based systems," Mr. DeLegge said.

Mr. Riphagen noted that ink makers are looking for high apparent viscosity at low and high shear rates for fast speed presses and flowable inks.

"Much of our developments in plasticizing polyurethanes have centered on the recent past in ensuring that the customer receives cost-effectiveness, offering solventless systems and improved press stability," said Mr. Wicken. "This trend will continue. In film-forming polyurethanes, we have concentrated on providing products that are not only for mono-component lamination inks but also usable with other binders."

"Particular areas of focus in resin technology include highly soluble and highly structured phenolic resins for heatset and sheetfed applications," said Brad Crocker, business manager, inks and coatings for Arizona Chemical. "We think this technology improves ink printability as well as increases formulating flexibility."

"I think that ink manufacturers are looking for the best combination of economics and performance," said Dennis Butcher, applications manager for paper and graphic arts for BFGoodrich. "There is some interest in non-absorbent films and foils, and there seems to be interest in a lot of new technologies such as the hybrids."

Solvent- and water-based research continues to be at the forefront of resin development, as ink manufacturers create formulations for these specific areas.

"Solvent-based technology was forecasted to decline for many years, but we have yet to see the onset of that decline," said Mr. Gallouedec. "Actually, while waterborne technology remains one of the fastest growing graphic arts market segments, some water-based formulators have started to convert back to solvent technology. The two primary reasons behind that trend shift are that solvent-borne inks still offer superior performance, especially on flexible substrates, and solvent recapture equipment is getting more efficient and sometimes less costly than the production lines upgrades and/or changes required by the switch from solvent to water."

"Water-based resin manufacturers continue to develop new products to meet the needs of the printing ink industry," said Mr. Grandke. "The developmental areas are in improved pigment dispersion performance. We can now make a water-based dispersion containing 40 percent organic pigment at a desirable 4:1 pigment to binder ratio and a viscosity under 500 centipoise. These dispersions are not only low viscosity but also shock-stable, non-settling and compatible with most ink making materials.

"Water-based resins manufacturers are also working on higher product resistant resins and emulsions," Mr. Grandke said. "This development work will allow water-based inks to enter areas traditionally dominated by solvent-based inks."

Improvements are also expected in the areas of flexo and UV, as ink formulators continue to explore these fields.

"We expect strong growth in the area of polyarnide resins for flexographic and rotogravure laminating inks due to new technologies that offer improved printability, bond strength and nitrocellulose compatibility," Mr. Crocker said.

Mr. O'Toole said that a growing area of interest are low viscosity, high-performance products to meet the growing needs of the UV flexo market. Mr. O'Toole noted that Cognis expects to unveil new specialty resins in late 2000.

Working with Customers

Working with customers to create new products is an increasingly important facet in business. This certainly holds true with resin manufacturers as well.

Mr. Wicken cited improved performance at ever lower costs, an initiative in development programs anticipating changing needs, and closer technical contact to minimize delays in new product introductions.

"We are dedicated to working closely with our customers to ensure we provide products that meet their needs," said Mr. Wicken.

With globalization, it has become increasingly important to have the ability to reach customers throughout the world.

"Lawter International has experienced and knowledgeable research and development staffs in the U.S., Europe and Asia," said Jack Baarends, VP of R&D at Lawter International. "Our R&D people are focused on working closely with ink producers on a global basis to develop new products, improve existing products, solve day-to-day problems as they occur, and manufacture those products more efficiently and economically. Many times we will work through our vehicle division with their customers so that we are involved from the resin polymer through to the ink."

"Our customers are always looking for new ideas to address problems and Rohm & Haas is recognized as an innovative technology leader," said Ms. Hartschuh. "The global printing ink manufacturers are looking for partners that also have a superior global and manufacturing supply network.

"Printing ink companies are also looking for quality, close technical support, with fast turn-around time, and resin companies that can offer a wide range of products covering more than just one or two families of graphic arts resins," said Mr. Gallouedec.

"Cognis' new product development effort is definitely market driven," said Mr. Gallouedec. "The new products developed over the last couple years have been the result of customer inquiries, for added performance in existing applications and/or for usage of existing resins and additives in new applications. Due to the global position of Cognis, we are present on all five continents. This allows Cognis to become aware of technological market shifts and to transfer technology from one market to another whenever appropriate."

"We at Johnson Polymer work closely with our strategic customers," said Mr. Grandke. "Our customers are a valuable source of applications and market knowledge. Our customers are key to our new product development effort. Their role can take many forms; from evaluating and giving us feedback on early prototypes to joint product development efforts."

As the printing ink industry moves forward, it is even more imperative to keep prices down while improving quality and services. Ink companies will continue to work with their suppliers in all phases of development.

"Printing ink manufacturers are looking for higher value products," concluded Mr. Grandke. "Ink companies want products that will allow them to cut cost from their system. Lower overall cost is a strong driver in the industry today. It is the resin manufacturers' challenge to achieve higher performing products at equal costs or equal performing products at lower costs."

"Printing ink companies are looking for resin manufacturers who understand the reality and the challenges of printing presses," said Mr. Gallouedec. "A deep knowledge of the correlation of the resin physical chemical properties and their impact on the printing performance is essential, so that new products can meet the ever-changing demands of the printing industry -- new substrates, faster lines, more universal inks capable of printing on multiple substrates and offering a wide window of operations to allow variations of printing conditions without variation of printing quality."
